Abstract

A PROCESS FOR PRODUCING HINOKITIOL WHICH COMPRISES THE STEP OF OBTAINING L-ISOPROPYLCYCLOPENTADIENE FROM CYCLOPENTADIENE AND AN ISOPROPYLATING AGENT REPRESENTED BY THE GENERAL FORMULA R -X WHEREIN R IS AN ISOPROPYL GROUP AND X IS A HALOGEN ATOM, A TOSYL GROUP OR AN ALKYLSULFONATE GROUP (FIRST STEP), REACTING THE L-ISOPROPYLCYCLOPENTADIENE WITH A DIHALOKETENE TO OBTAIN A KETENE ADDUCT (SECOND STEP), AND DECOMPOSING THE KETENE ADDUCT (THIRD STEP), SAID FIRST STEP COMPRISING THE FOLLOWING THREE STEPS: A) A STEP OF PREPARING A CYCLOPENTADIENYL METAL FROM CYCLOPENTADIENE AND AT LEAST ONE OF A METAL HYDROXIDE OR A METAL ALKOXIDE (PREPARATION STEP OF CYCLOPENTADIENYL METAL); B) A STEP OF OBTAINING ISOPROPYLCYCLOPENTADIENE BY REACTING THE CYCLOPENTADIENYL METAL WITH THE ISOPROPY- LATING AGENT IN THE PRESENCE OF AN APROTIC POLAR SOLVENT CAPABLE OF FORMING TWO LIQUID PHASES WHEN MIXED WITH ISOPROPYLCYCLOPENTADIENE AS A PRODUCT (ISOPROPYLATION STEP); AND C) A STEP OF ISOMERIZING 5-ISOPROPYLCYCLO-PENTADIENE IN THE ISOPROPYLCYCLOPENTADIENE SELECTIVELY TO L-ISOPROPYLCYCLOPENTADIENE WITH HEAT (ISOMERIZATION STEP).
